Crank and piston options/ will 4 mil stroker

[brilei5]

Well here is the deal. The left side crank bearing is toast. Thankfully though I caught it soon and the only damage other than the bearing is some detonation on the left side piston crown around the edges. So I am going to replace the pistons and I think buying a new or reman crankshaft is the way to go. I have too much invested to take a chance on the other bearings being bad. So, what I have is a long rod motor with a woods / low to mid port job with 67.5 mm bore. My question is if I go with a 4 or 5 mil stroker crank will my port configuration still work? The exhaust port hieght is 25.5mm I can give the other measurements if need be. Also I am a woods guy (one of the few on a Banshee) . So I run stock carbs to keep the low end strong. Can stockers handle a stroker? I kno strokers are more powerful but is it worth the investment for it for a woods/ mx quad? Your opinions are will be appreciated. Thanks

only if you use a spacer plate, which i wouldnt recommend.

yes stock carbs can handle a stroker, but for full potential 33, 35 or 39mm carbs would need to be used. i dont personally think you need a 4mm for woods riding, but if you go that route have it done right and either get new jugs and have them ported or have the existing porting redone to work with the stroker setup.

Thanks for the reply. That is what I suspected. I will just stick with my current set up, I am not at all unhappy with it. I just figured if I am buying pistons and a crank anyway it was worth asking. Thanks
